a To all whom it may concern.-

' Be itknown thatl, (hpunLns t). L. (An- DELL, a citizen of the UnitedStates. and a of mechanism for. packing the folded sheets 1 resident ofPearl River, ltocklaml county. State of New York. have invented certainnew and useful lmproven-ients 1n lackmg- Boxescfor Folding-Machines. ofwhich the following is a specificatior. I

The presentinvention; relates to the type of proper dimensions tocoiiperatef with the receiving table or platform when adjusted toreccivethe largest size of folded sheets or' signatures for whlchadapted. ,NVith such packing mechanisms. the stack retaining barriermust have a sut-licient length of stroke into and out of operativeposition to clear the receiving, table or platform wheniit is inposition to receive the largest folded sheets or signatures. Thisrequirement as to the stroke of the barrier produces an unnecessarily.long stroke when the receiving table or platform is receiving asmallerfolded sheet or signature.

The object of the present invention is to improvethe "construction ofsuch packing mechanisms for folding machines by which thest'ro'ke ofthe. stack retainingbarrier may' be reduced toa minimumwithontinterfering with the adjnstab'ility of the packing box't'o suitvaryingsizes ,of folded sheets or signatures. 'In accomplishing this object. Ihave produced a packing box in which the stack retaining barrier ismounted upon the reeeiving't-ableor platform and is vertical] adjustabletherewith, and the distance which. the barrier tingers project abovethe. surface of the table or platform, being independent of the variousadjustments. The operating jmechanism for the stack retaining barrierincludcscertain adjustable parts in conne'cthe mechanism isSpecification of Letters Patent. Application filed June 1. 1911 SerialNo. (1609.

'lhese dclivcuv lt)lltt' 5are suitably journaled in the frame 1 ol the. folding machine. Below therollers 5 is a transverse shaft ltlse'cured at its ends in suitablebran-kets indicated at ll and supporting between its ends a plurality ofdepending gravity dogs 12 which are free to more in oue direction underthe action of'fhei packer fins gcrs and are held against moveincnt inthe opposite direction by su'itable shouldered collars -to support thestack of folded sheets or si natures at the top to maintain them out ofthe path of succeeding sheetsorsig natures which nredroppc'd'from'thedelivery rollers This part of the mechanism isvcry common in the art. I

15 is the table or platform of the packing box upon which the successivefolded sheets or signatures are dropped on edge. This table or phi-tform15 is mounted upon suitablesid brackets indicated at ltl which areformed with outwardly presented ears 17.

having vertical guide openings through which extend the vertical bars 18mounted at their ends "I brackets It and 20 secured nus the verticalbars 18 has rack teeth 18 cut" into it.' A transverse shaft 21 is freelyjourthe rack teeth 18 naled in bearings formed upon the ears or lugs 17and has small gears or pinions 22 cut upon it in proper position to meshwith just referred to. The shaft 21 is provided at one end with asuitable hand wheel 23by which it can be rotated. Adjacent to the handwheel 23, shaft 21 is provided with a ratchet wheel 24 with whichengages the gravity awl or dog 25 journaled at 26 upon one the tablesupporting brackets 16. 21 forwardly the table 15 can be raised upon thesupportlng bars 18 to bring itcloser' to the'delivery rollerspreparatoryto receiving smaller folded sheets or signatures. By disengaging theshaft121 can lower the table sheets or signatures.

be rotated rearwardly to to suit larger folded The end of thesupport-lngtableor latform 15 directly beneath the delivery r0 lers 5 isformed with a seriesof parallel slots 15- in which the horizontally;reciprocating packer fingers operate in the. manner presently to beexplained; The slotting of the of sup-' end of the table 15 provides aseries orting fin ers 1 5, each one ofwhich is ormedwit a verticalopening' lii -for the passage of one of the rods of theverticallyreciprocating barrier which will now be descr' bed. p

deemed to and depending from the table supporting brackets '16 are thebrackets 30 formed with hearing cars 31 in which re-- I ciprocate thevertical g '-ide rods 32 having secured to them between the bearings 31the sleeves 33 formed with inwardly presented bosses 34 between whichis-su pported a transverse bar This bar 35 carries a plurality ,ofcollars 36 from each one of which projects a barrier rod 37. JTheserods37 extend upwardly from bar 55 passing 1 through openings in-guide arms38 projecting from a metal plate 39 extending transversely beneath thetable or platform 15-and secured at its ends tothe supporting brackets16 of-the table'i'. Thebarrier rods 37 also projectthrough the openings15of the-table arm's 15 above referred to.

40, 40' are curved bracket arms secured to the table brackets 16 andsupporting in their depending ends a transversely extending rock shaft41, which carries adjacent to its ends inside of the vlora'clmts 40 therock arms 42 supporting at their; ends the hanger .,.links 43'whichare-'journaled upon the bar .The rock shaft 41 has. keyed to one end arock ar-n'i" 4l'r'connected by link 46 which has swivel connection-+47with a, rock arm 48. ad ustably mounted upon a vertical rock shaft '49-jpurnaled in bracket bearings 50 By rotating the shaft the dog 25 fromthe ratchet 24, shaft 49 is keyed a rock manner by -means not secured tothe folding machine frame. This vertical rock shaft 49 has a splinegroove 51 extending from end to end, and the adjustable rock arm 48carries, a key screw 52 which engages the spline groove 51 for keyingthe rockshaft 48 upon shaft 49;- A bifurcated bracket arm 53 extendsfrom one of the table brackets 16 and embraces the verticalrock shaft 49wlth an ear resting 4 upon each side of the hub ofrock arm 48 so thatupon loosening the key screw 52 and adjusting the table vertically, saidrock arm 4-8 will be adjusted upon'the shaft 49 to suit the adjustmentofthe table, the other operating parts of the reciprocating barrier justdescribed moving with the table becausesupported therefrom. v

At the lower end of. the vertical rock arm 55 having a. with a rockarnif57 serod 56 connecting it I rock shaft 58 carrying cured to atransverse at its opposite end a rock arm 59 from which extends avertical pitman 60 carrying a guide yoke 61' erative relat'on shaft 62.a e shaft 62 is journal'ed 1n suitable bearings upon vthe frame of thefolding mach'ne; and is I, operated in any sh Wu", A spring actuated rod65 engages the rock arm 57 and extends th'rdugh a guide bracket 66 formoving the; described mechanism in opposition to the ca 64."

The packer fingers up through the slots 15 15 and are mounted at theirlower ends upon indicated at 7 0 project adjust-ably secured uponciprocating bars 73 which are freely journaled in the brackets 74 and75. One of the 'bars 73 carries" an adjustably securedv sleeve 76 towhich is. pivoted a rod '77 extending therefrom toa rock 'arm 78 fixedto, atrans verse r.o ck shaft 79 carryingat its opposite end-a rock armpit-man 81 havinga guide y0ke 82 guided upon the'sh'aft 62 above"referred to., This guide-yoke 82 carries ananti-friction roller 83which operates in peripheral-"contact with a controlling cam 84 keyed totheshaft-62.

Aspring actuated rod 85 is connected with the rock arm and extendstherefrom through'a' guide bracket BG'fOrcoGperating wvith; the cam 84inproducingthereciproeating movements of the packing fingers. v

80 connected with a'vertic'al guided upon a shaft 62 and I supporting ananti-friction roller 63 in opto a cam 64 fixed upon said suitable formedin the table a cross bar 71 formed with guide sockets 72 thehorizontally re In the operation of the improved'packing mechanism, thesuccessive folded sheets or signatures drop from the rollers 5 to'theplatform 15 which has previously been adjusted to size of sheets orsignaturesheing operated upon.' As each folded sheet or signaturereaches the table" 15, the barrier fingers 37 are" drawn downwardlybeneath the? surface the proper'heightto receive the of the table andthe packer fingers 70 are moved inwardly in t he table slots, to carrythe last delivered folded sheet or signature horizontally, along thetable'against' the stack or row .of previously. forwarded sigma: tures.Immediately after the ;movement of the; delivered signature past the hneof thev barrier fingers, 3,7, the fingers 37 aga n projcctoabove thesurface of the table and the packerfingers..are drawn back, the tingers37 engage the last forwarded folded sheetLorsignatureadjacent to thetable and retain the stack in place. .The gravity retaining fingers 12yield to permit the action of the packer fingers and,upon the return ofthe packer fingers avay from the stack,

saidflfingers 12 engage the upper edge of the last sheet or signatureand. retain the stack in position at the top. i

The important feature ofnovelty in my present invention is theconstruction and arrangement of the parts of the packing mechanism bywhich the table and barrier fingers can readily be adjusted to suit anysize of folded sheet or signature to be delivered by the foldingmachine. It is de-' sirable to confine the movement of the bar rierfingers to as small a compass as practical,

and to have them project uniformly above the surface of the table whenthey are in retaining position, and for this reason. it is importantthat they be adjusted with the adjustment of the table. This structureis of great advantage over structures heretofore employed in which thetable alone has been adjusted and' the barrier fingers made of extremelength soas to project an extreme distance above the surface of thetable when operating upon large sheets. since in this old form ofconstruction, it is necessary to give the barrier fingers a long strokeinto and out of operation to suit their operation tothe handling of thelargest folded sheets or signatures. In my construction, the ver ticalstroke of the barrier fingers is the minimum stroke required to movethem into and out of operative position and the stroke the same whetheroperating upon large or small folded sheets or signatures.
